The Orioles recalled Raquet from Triple-A Norfolk on Tuesday.
Raquet was acquired via trade from the Cardinals on Monday and will go directly onto the Orioles' roster. The left-hander made two scoreless appearances for St. Louis last season and had allowed one run with a 3:0 K:BB over his first three innings with Triple-A Memphis this season. Raquet will give manager Craig Albernaz another lefty option in the bullpen.
